Ivan's Hammer refers to the theoretical use of a natural asteroid or meteoroid as a Weapon of Mass Destruction in a first-strike role. The concept can be traced back to the 1960s.[1] During the late 1950s and early 1960s a number of science fiction writers used the concept in story ideas, most notably Robert Heinlein in The Moon is a Harsh Mistress where a rebellious Lunar colony uses large payloads of mined ore to bombard Earth from the Moon.

A RAND Corporation study from 2002 [2] also discusses the method and feasibility of such an application, and Carl Sagan discusses the idea at length in Pale Blue Dot.[3]
